"On November 7, the British Army's Ajax armored reconnaissance vehicle completed its manned firing trials with its turret, which utilizes the CT40 autocannon. While this may seem unremarkable on the surface, it marks another step towards the first real adoption of a gun using cased telescoped ammunition (CTA) technology, which has been in development since the 1950s. The technology was considered for many uses in the past, including for the M2 Bradley. But only recently has it reached technical maturity, and it is now being seen as a serious way to increase firepower in autocannons and infantry weapons. Cased telescoped ammunition was invented in 1954, in a U.S. Air Force laboratory. The idea is very simple: instead of having the projectile protruding outside of the cartridge, as in standard ammunition, CTA places the projectile inside the cartridge. In such a configuration, the projectile is considered to be "telescoped" inside the cartridge. When a CTA round is fired, a small booster charge pushes the telescoped projectile out of the casing. Once the projectile is in the barrel, the remaining propellant in the casing ignites, generating the pressure required to push the projectile down the barrel. The timing between the booster charge and the main propellant is critical for the CTA to work. CTA technology decreases the size of the ammunition and allows it to take the form of a simple cylinder, unlike other ammunition types, which are more complex. This allows for a decrease in weight, more compact ammunition, and smaller and less complex feeding mechanisms…." Main page link Amicalement Armand |

One more thing to go wrong when you actually have to use it. |

Considering how complex sabot separation is, and how much time and money it took to make it really reliable, this is simple by comparison. Not all that much more.complex than a primer. Fir autocannon, the increased reliability of the gun itself is likely to more than make up for even pessimistic reliabilities of the telescoped ammunition. And I'm generally wary of the claims for new technologies. |

Also, the CTA40 has a much simpler feed system, courtesy of the basic shape of the ammo. Kinda cool, actually, the feed goes right through the trunnions, so there's no feed limitation on gun elevation. |
